NON-REFILLAIBLE BOTTLE.

Specification of Letters Patent.

Patented May 5, 1914.

To all whom it may concern Be it known that I, MAX P. SCI-HILL, acitizen of the United States, residmg at San Francisco, in the county ofSan Francisco and State of California, have invented new and usefulImprovements in Non-Refillable Bottles, of which the following is aspecification.

The object of the present invention is to provide a cheap and simplenon-refillable bottle of cheap construction while effective for thepurpose desired.

In the accompanying drawing, Figure 1 is a vertical section of the upperportion of a bottle equipped with my invention; Fig. 2 is a similar viewof the same in an inverted position; Figs. 3 and a are cross sectionalviews on the lines 3-43 and tl respectively of Fig. 1.

Referring to the drawing, 1 indicates the neck of a bottle to which myinvention is applied. Within said neck is a casing 2 of a valve chamber,the lower portion 3 of which is cylindrical and formed at the bottomwith an outwardly extending flange 4, spun around an apertured circulardisk 6, said flange being contained within a groove .7 formed in theinner surface of the neck of the bottle, said casing being securedwithin said neck by a ring 8, of absorbent material, saturated withcement. Secured to the centor of said disk, and extending upwardlytherefrom, is a stem 9, which stem enters a cylindrical socket formed inthe center of a frusto-conical .valve 11, of cork or similar lightmaterial, the base of which valve, when resting upon said disk,completely closes the apertures 12 therein. Upon said valve rests a ball13, of glass or similar non-corrosive material, the casing having aspherical top to fit snugly around said ball. In the wall of said casingapertures 14; are formed by cutting the metal of the casing along threesides of a rectangle and pressing the metal inward about the fourth orlowest side, as clearly shown in Fig. 1. The metal pieces forced inwardthus serve as protectors, preventing the passage through said apertures14, and access to the valve of wires or other instruments.

hen the bottle is inverted, the ball 13 rolls said valve, through theapertures 14, and out between the casing and the neckof the bottle.

A very important feature of my present invention resides in the factthat the valve 11 is made wholly of cork, and has no metallic partsattached thereto or movable therewith. Therefore it is very light, andconsequently in pouring the liquid out of the bottle said valve vibratesvery easily and rapidly. If this valve were of considerable specificgravity, as when it has attached thereto metallic parts, as in my U. S.Patent No. 1,019,585, then'the eifect would be that, in pouring liquidfrom the bottle, very considerable suction would have to be produced inthe bottle before the valve would be drawn by said suction back to itsseat. hen it would be so drawn to its seatit would not be dislodgedtherefrom by the weight of the liquid. With my improved valve this isnot the case, for, because of its being lighter than the liquid beingpoured out it is drawn toward its seat by a very slight suction, whileit is surrounded by the liquid being poured out, but, as soon as thisliquid has left it, it is forced away from its seat by the liquid in thebottle, air passing by the valve into the bottle to reduce the suctionin the bottle. Thus there is set up a very rapid vibration of the valve,the movement from its seat being caused by the movement of the liquidand the motion toward its seat by the suction produced by the dischargeof said liquid. But, on account of the valve being very light, thisvibration isproduced easily, by only a slight difference in pressure inthe interior of the bottle, and consequently the suction in the interiorof the bottle is never sutficient to permanently hold the valve to itsseat. This would not be the case if the valve had metallic partsattached thereto, but the valve would remain oil its seat until asufficient suction was produced to draw it to its seat and when oncedrawn it would be held tightly thereon. It is for this reason that Iemploy the stationary stem 9 by which the valve is guided in itsvibration, instead of employing a metallic stem movable with the valveto guide it in its vibration.

My improvement also permits of great economy in construction. In myformer device of Patent No. 1,019,535, in which I employed a valvehaving a metallic plate as a part thereof, the manufacture of said plateand the securing it to the buoyant part of the valve, was far toocostly, and I can make a large number of my present valves at the samecost of a single one of the valves shown in my former patent. Thepresent construction also permits of the valve seat having a largenumber of holes and therefore permits of a freer flow of the liquid. Itwill be seen the means for preventing refilling are very effective andat the same time cheap and easily made.

I claim 1. In combination with the neck of a bottle, an apertured casingsecured therein, an apertured disk secured thereto, a stem secured to,and extending upwardly from, the disk, a valve made wholly of corkslidable on said stem within the casing and arranged in its seatedposition to close the apertures in the disk, and a ball Within thecasing and resting on the valve when in its seated position.

2. In combination with the neck of a bottle, an apertured casing securedtherein, an apertured disk secured thereto, a stem secured to, andextending upwardly from, the disk, a buoyant valve slidable on said stemwithin the casing and arranged, in its seated position, to close theapertures in the disk, and a ball within the casing and resting on thevalve when in its seated position, said casing having integralprotectors, each protector extending inwardly from that side of theaperture which is nearest the valve.

in testimony whereof I have hereunto set my hand in the presence of twosubscrib ing witnesses.
